  • This form prints on the diaphragm 6, which is biased by the spring 7 such that when a pressure of about 1.4 bar is reached, the pin 13 moves the valve lever 12 so that the valve 11 closes and the gas supply is stopped.
  • the pre-pressure reached reaches the valve 25 via the gas connection channel 14. This is preloaded by the spring 28 so that no gas can escape.
  • the relatively strong spring 7 in the housing chamber 4 is also relieved by the vacuum coming via the vacuum connection line 15 from the carburetor 17 via the membrane 6 in such a way that the pressure in the gas collection chamber 8 drops.

  • the negative pressure remains relatively high despite the throttle flap 18 being open.
  • the gas pressure in the gas collection space 20 remains relatively low until the engine heats up and the throttle valve opens. This prevents the engine from performing at full power before it heats up.

  • the spring 45 presses the closure valve 49 firmly against the end 50 of the connecting tube 47.
  • the control rod 46 transfers the end position to the closing flap 48 in order to completely close the passage opening in the partition plate 19, depending on the position of the upper stop, by means of the adjusting screw 34 or to keep a gap open depending on the engine requirements.
  • the negative pressure present under the throttle valve is supplied via the negative pressure connection 16, the negative pressure connecting line 15 and the line 42 to the upper side of the membrane 44 in the membrane box 41.
  • the spring 45 is loaded so that the closure valve 49 with the control rod 46 opens the closing plot 48.
  • the spring 45 is chosen so that the sleeve of the closure valve 49 at the end 50 of the connecting tube 47 does not allow air passage.
  • the mode of operation is reversed when the throttle valve is closed.
  • the pressure under the throttle valve rises higher than in the idle position.
  • the membrane 44 Through the membrane 44, the spring 45 is compressed and tensioned so much that an opening gap is formed between the closure valve and the connecting tube 47.
  • the closing flap 48 is opened further and, since the connecting tube 47 is arranged at the lowest point of the space 35 of the evaporator, the oil separated from liquid gas during the evaporating process flows through the line 43 ob in this position.

  • the manifold 67a receives an additional air supply from the carburetor 17.
  • the resulting gas pressure affects the various membranes of the evaporator in the manner described above.
  • the conical valve body 54 is supported by the weak spring 53 via the membrane 36 on the end 39 of the longitudinally displaceable pin 27, whereby a weak residual gap is formed in the opening 55.
  • the slight negative pressure that occurs cancels the preload of the spring 22 in the gas chamber 5. Since the line 67 is connected under the throttle valve 18 cm carburetor, the relatively high negative pressure is passed via the premixing nozzle 63 via the lines 62 and 66 to both sides of the membrane 36 of the second pressure reduction stage. Due to the remaining gap on the valve body 54 of the diaphragm box 51, this pressure also acts on the diaphragm 52.
  • the suction effect is supported by the bypass line 57 so that, despite the fresh air opening via line 59, so much negative pressure is generated that the cone valve 54 moves in such a way that there is a gas flow required for idling.
  • the quantity of gas corresponding to the engine characteristics can be set continuously by means of the menganegrredungsstellrorou 58.
  • the pressure drops below the throttle valve.
  • the magnitude of the pressure has no effect, since the pressure is likewise passed through the premixing nozzle 63 onto the upper and lower sides of the membrane 36, and the effect is thus equalized.
  • the air that is now sucked in passes through the measuring nozzle, the negative pressure which arises in this nozzle passing through line 61 to the membrane box 51 will wear.
  • the resulting dynamic pressure is brought through the supply line 59 into the space 56 of the membrane box 51.
  • the combined action overcomes the tension in the spring 53 and opens the cone valve 54.
  • the air now flowing into space 35 with dynamic pressure causes an increase in pressure. This is transmitted through line 62 to the premixing nozzle 63.
  • the equilibrium above and below the membrane 36 is now changed in accordance with the air throughput.
  • the evaporator can be adjusted continuously by adjusting the displaceable adjusting cone 65 of the premixing nozzle 63 and the adjusting screw 60 in the dynamic pressure line 59.
  • the pitot tube 68 consists of a pitot tube 68, which is arranged in the interior of an air supply line 69 to the air filter (not shown).
  • the pitot tube 68 is connected via a line 70 to the dynamic pressure line 37, a relief opening 72 being changeable with the aid of a relief adjusting screw 71 and being adjustable to the special flow conditions of the different engines and vehicles.
  • the air flowing in through the air supply line 69 generates a dynamic pressure in the pitot tube 68, which pressure is transferred to the gas chamber 5 via the lines 70 and 37.
  • the dynamic pressure acts to support the back of the membrane 36, its intensity being adjustable by actuating the relief tube 71. If, when the throttle valve is closed, an increased dynamic pressure from the mixer reaches the lower side of the membrane 36, this is compensated for by the supply line 37 from the nozzle to the top of the membrane 36. As a result, the engine holds as much gas as is possible by prestressing the spring 28. The engine does not set qus and is immediately fully loaded again.
  • the Miocher 32 shown in FIGS. 1 to 4 still has an annular body 73 with an inner collecting chamber 74 in FIG. 7.

  • the intake air flows in through the circular air inlet formed between the annular body 73 and the baffle plate 77, the air inlet opening being adjustable by means of the threaded pins 78.
  • the relatively turbulent air flow coming from the air filter is aligned in a laminar manner and strikes the deflection nose 76.
  • the acceleration generated as a result of the narrowing of the cross section creates a negative pressure which is further reinforced by the slipstream behind the deflection nose 76. This negative pressure is transmitted through the outlet slot 75 to the collecting chamber 74.
  • the flow must be deflected in the space enclosed by the ring body.
  • a guide flow is let in through the small central bore 81 in order to calm the vortices formed during this deflection.
